It investigated the effect of rolling deformation modes in the ferritic temperature range on the formation of the structure and properties of ultra-low-carbon steels. It was found that as a result of processing, which includes rolling the studied steels in two passes and cooling with a furnace, an uneven structure and the following set of properties were formed: Rm = 225–260 MPa ; Rv = 165–195 MPa ; Rm/Rv ~ 0, 72–0, 73 ; A = 25-32 % ; HRF 73–75. The results of the work make it possible to determine the optimal composition of ultra-low-carbon steels, make the choice of rational technological modes of obtaining thin-sheet rolled products and so on. |
